Disable webmail for other domains other than the primary.

How do I turn off webmail for other domains? I have a couple of domains, and each domain gets webmail at: mail.domain-name.tld. I want to turn off this feature because I have my own ODIC provider and would like my users to access webmail only through the main/primary domain.

I don’t understand. your mailcow server has A record for like mail.yourdomain.com
your primary maildomain has MX record for yourdomain.com, pointing to mail.yourdomain.com
Any other mail domain has MX record like otherdomain.com pointing to mail.yourdomain.com
This way, all users can only use webmail via mail.yourdomain.com.
Why did you configure the other SAN (CNAME) for the other domains in the first place, if you do not want the users to use them? They are not necessary.
